To all whom it may; concern lle it. knovvn that l, JEAN citizen of? the United States, lfirnsotu. in the county of Biff Stute or' l-"lorde. have invento^ useful 1inprovements in {rtrllr nhieh the following is :i speci .y

The present invention relntcs te carbure ters.y und one of the prima objects is to provide ineens, whereby `.vill he admitted to constitute a puit ol' the charge, such water f :ommingling with the air prior to the introduction of the hydrlilcarbon fuel.

Another object is to provide a carburetor, hy menos of wh'z :h fuel otd'ierent characteristics, is for exam-ple. kerosene oil and gnsolene may he used, provision being made Alor :i proper supply of euch fuel and the n ecessury regu lation thereof.

lr. he accompanying drawings: Figure 1 is n view partly in section and 'partly in ele vation of a carburetor, embodying the pres`n ent intention. Fig. 2 is n top plan view of tho sume with the noverof the casing removed. Fig. 3 is n detail sectional vievv illustrating the controlling means for the fuel. Fig. 4 is a detail sectionalview on the line 47741: of Fig. 1. Fig. 5 is a detail view oi' one of the shut-ol valves for the fuel. Fig. 6 is n detail sectional view of the means for varying the resistance of the tension spring that opposes the nir inlet controlling vulve. Fig. 7 is a detail sectional vien7 of one of the supply controlling valves und its associated parts. Fig. 8 is e similar view ot the other supply controllingr valve` Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, a raising is employed comprising u Cupshnped body Si) having en integral top flange 10, to which is secured hy means of sen-ws 11, or other suitable fasteners, n removable cover l2A This cover is provided with u central upstanding nipple 13 that is internally threaded, ns shown nt 1.4,'vvherehy it may he suitably coupled to nn engine or other article to receive the prepared charge. The body 9 of the casing is provided with n central upstnnding charge-forming und directing! ronduit l5 that depends from the liottom of said casing in the form of un exteriorly threaded boss 16. while the upper end fits snuglyln a recessed seat 17 formed in the under side D.

of the cover or cap 12, so that the nip le 13 constitutes un extension or partL `o 'fsaid vonduit. The body of the casing is furthermore provided with e tre.. sverse partition 18 arranged radially ofthe conduit l5, und separating the interior of seid casing into two seperate compartments or reservoirs 19 and 20, respectively intended for holding predetermined amounts of fuel of different characteristics, as for exnmple kerosene oil and gnsolene. Euch compartment is supplied with Yfuel through a laterally extending nipple 2l that can he connected by a pipe as 22, to any suitable source of supply. Each nipple at its juncture with the casing is enlarged, as shown at 3, and is provided in its top with an opening 24 closed hy a screw csp or pl ug The nipples are interiorly threaded to receive plugs 26 having supply orts 27 therethrough, the inner ends of suc. ports constituting valve seats, against which abut tapered valves 28. These valves are carried by stems 29 having bull heads 30 at their inner ends that are received in sockets 31 formed in hell crank arms 32. The said balls are retained in the sockets by screws 33. The bell crank arms 32 are journaled on suitable pivots 34, on which are also journalcd other crank arms 35, to which are fastened, by screws 36, or other suitable devices, arcuate floats 3,7 that partially surround the conduitl 15. The two arms 32 und 35 are thus relatively ed'ustable und .ire adjusted on screws 38 t at are threaded through the arms 35 and are journ naled in curs 39 formed upon the arms 32. These screws ure readily accessible through the openings 24 when thercaps 25 are removed, as will he evident, and it Will thus be seen that by rotating seid screws in one direction or the other, the angular relation of the arms 32 and 35 can he altered, so that the level of the liquid fuel can be maintained at any height desired.

Arranged axially Within the conduit 15 is a fuel-discharge nozzle 40 that is carried oy transverse pipes 41 extending through the Walls of the conduit and through the ivalls of the casing 9. The outer projecting ends of said pipes are provided with packing glands 42, through which extend the stems 43 of needle vulves 44, said stems having exposed actuating hoods 45. B v referring particularly to Fig. 3. it will he noted that valve seats 46 are employed for the needle can he easily controlled.

valves 44:, and it will also he noted that the "ports controlled by such ent diameters, depending upon the character of the fuel used. The pipes (l1 respectively communicate with the compartments 1.9 and valves, are of differ 20, through lateral inlet portsfl, and these ports are controlled threaded, as shown at the casing wall il in glands 44a. i

he outlet end oi' the conduit 15 is conA trolhd hy a throttle valve i7 journaled in the N4pple lll and having its shaft 4S provided 'with an exposed actuatin arm 49. The air inlet to seid conduit is isposed in angular relation thereto, as illustrated at :30, :ind is presided with u central guide ele` ment 5lv having :i valve ste1nreeei\ing bore M. The inner nfl of the inlet is provided with a anita le wlw wat h3., with which coopere tes an inv; e rf l lj.' ling valve 5l. lim ing stem ofi, one

A coiled spring 5e, interpw` lfetweon and bearing against the volw 5l nml the screw 5G, serves to normally hold sa ,i wire in its closed positien. lt will he evident that by turning the screw 5h in one direction or the other, the tension of the epi-ing: .38 against the valve n'nrv bc varied. The guide member 51 is furthermore prtwideil alongside the bore 50 with a wen inlet port SSL with which communicate ine here of a nipple G0 that can be connected to any suitable source of water supply. i The discharge end of the port 59 is controlled by the valve 54, and a needle valve (S1 ,is also employed for controlling the amount of water del; red or for shutting it oli altogether. .It n oe evident that with this structure, a spray of water will he adlnitted to the conduit with the air at every 'ime a charge lis drown through the carburetor, and 'the amount 'of water so admitted It .vill also be evident that different grades or different charr acters of fuel may be utilized with the same carbureter by shutting off one or the other of the compartments, and the supply from either compartment can he controlled and modified as desired. The level of the fuel in each compartment is at all times maintained by the float-controlled valve, and this level can be varied at an time by relatively adjusting the float andyvalve-carrying arms 32 and i It will also4 be evident that the parts are always readily accessible, so that they can be inspected, cleaned, and if necessary replaced with ease and expedition.

From the foregoing, it is thought that the construction, operation and many admi;u tages of the herein described invention wll he apparent to those skilled in the art,wit out further description, and it will be understood that various cl'ianges in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a carbureter, the combination with an nir conduit having an inlet, of a central guide element in the inlet having a steinn receiving bore and av water discharge port located in said element alongside the bore, means for delivering,r water to the port, a needle valve in the guide element controlling the water supply, an air valve control` ling both the air inlet and the water discharge port, said valve having a stem sliding in thc bore of the guide element, means for yieldingly holding the valve closed, and means for supplying fuel to the conduit.

In testimony whereof l have hereunto set my hand in presence of two subscribing witnesses. y
